SPECIFICATION forming part of Letters Patent No. 776,739, dated December6, 1904.

Application filed June 30, 1904- Serial No. 214,776. (No model.)

To It whom it may concern.-

Be it known that I, ROBERT R. HALL, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Eyeglasses, ofwhich the following is a specification.

My invention relates to improvements in eyeglasses, and pertainsparticularly to the Its object is to provide a small, strong, neat, andsimple spring connection whereby the lenses may be held securely inposition on the nose and close to the eyes and which will prevent thelenses tilting or drooping, as so often occurs with the largebow-springs.

It consists of the parts and the construction and combination of parts,as hereinafter more fully described and claimed, having reference to theaccompanying drawings, in which- Figure 1 is a front view of theeyeglasses fitted with my invention. Fig. 2 is an edge view of the same.Fig. 3 is a view on line y ;z of Fig. 2.

The lenses A are secured to the usual posts 2, which support thenose-guards 3 and also the ends of the spring a. The latter forms thesubject-matter of the present invention. The spring and guards arefastened to the posts by screws, as shown at 5. The spring has astraight horizontal portion arranged in a plane at right angles to theplane of the lenses and two short straight side or end portions 6 bentrather sharply and approximately at right angles, but ofi'set relativeto the central horizontal portion. As shown in Figs. 2 and 3, the endportions 6 lie within the plane substantially of the lenses, while thehorizontal central portion is projected forward beyond the plane of thelenses. The edges of the horizontal portion are concavo-convexed, atleast the inner edge of the spring is essentially concaved, as indicatedat 7, to afford the necessary Grecian to accommodate the nose and to letthe lenses come in close to the eyes, as they should. TlllS concavity 1sshown as extending beyond the plane of the lenses.

When the eyeglasses are in position on the wearer, they are supported onthe sides of the nose by the guards and on top of the nose by thespring. They are held on rigidly and cannot come off.

By using a small straight spring, as here 7 shown, with its resilienthorizontal portion at right angles to the plane of the lenses the latterare made to pivot in relation to each other in the same plane which thecorrect way for them to turn when being put on or oil? the nose.Furthermore, the axes of the lenses are kept in alinement when once theeyeglasses are fitted and do not tend to droop, as is the case with thelarger clumsy bows. The present spring being so small and with straightlines will not get out of shape.

lVith a pair of glasses of this type in position on the wearer verylittle metal is visible, simply the posts, the edges of the guards, anda straight narrow line indicating the spring across the nose.

Having thus described my invention. what I claim, and desire to secureby Letters Patent, is

1. In eyeglasses the combination with the lenses, of supportingposts,guards, and a spring having a horizontal, straight central resilientportion arranged in a plane at right angles to the plane of the lensesand in ad Vance of the plane of the lenses, said. spring havingstraight, rigid and substantially vertical end portions connected withthe posts, said horizontal portion having a concaved inner edge.

2. In eyeglasses the combination with lenses posts and guards, of aspring having a central horizontal portion bendable in a plane parallelwith the plane of the lenses but arranged in advance of the plane of thelenses and having short lateral substantially vertical portions engagingthe posts and made substan-
